Senior Flight Software Engineer

Responsibilities

• Own the architecture of major flight software subsystems, including timing, partitioning, and redundancy.
• Design and implement deterministic, real-time embedded flight software in C++.
• Design fault detection and response, including redundancy management, degraded modes, and lost-link behavior.
• Define software requirements and interfaces with avionics, GNC, and flight test, and trace them to tests.
• Implement GNC algorithms in flight code and verify them against simulation.
• Set testing strategy across unit tests, software-in-the-loop, and hardware-in-the-loop testing.
• Build telemetry, logging, and command paths between the aircraft and ground station.
• Lead aircraft software integration and support ground and flight testing, including travel to the flight test site.
• Set coding standards and review practices, lead design reviews, and mentor other flight software engineers.

Requirements

• Bachelor’s degree in computer science, engineering, or a related field, or equivalent experience.
• 5+ years of professional C or C++ development on embedded, real-time, or safety-critical systems.
• Experience owning a flight software subsystem or equivalent from architecture through fielded operation.
• Experience taking software through hardware integration and testing on a real vehicle such as an aircraft, spacecraft, or automotive vehicle.
• Experience designing fault detection and response for systems where failure had safety consequences.
• Experience leading design reviews and setting technical direction for other engineers.
• Preferred: flight software experience on aircraft or spacecraft; RTOS or bare-metal development; redundant or fault-tolerant flight computer architecture experience; DO-178C or ISO 26262 experience; flight or vehicle test campaign experience; Python for tooling, test automation, and flight data analysis; and clear technical writing.

Benefits

• Competitive salary and meaningful early-stage equity.
• Relocation support if applicable.
• Employee health benefit plans.
• 6% retirement matching.
• Flexible PTO.
• Free lunches, snacks, and a stocked fridge at company offices.
• AI tools and subscriptions.
• The role includes travel to the flight test site.
